The '''F''' class was a type of steam locomotive used by Swedish State Railways ({{langx|sv|Statens Järnvägar, SJ}}) and based on the Württemberg C. Eleven locos were built by Nydquist & Holm (NOHAB) between 1914 and 1916. It was primarily used on the main lines between Stockholm-Gothenburg and Stockholm-Malmö. It is one of the largest steam locomotives ever used in Sweden.

The superheated compound locomotive could produce {{convert|1140|kW|hp|0}}.

During the 1930s the locomotives became obsolete due to electrification of the main lines, and in 1937<ref>{{Cite web|url=http://www.svenska-lok.se/damp.php?s=19&litra=F&typenr=2|title = SJ Littera F ånglok F-lok}}</ref> were sold to DSB of Denmark, where they served as '''DSB Class E'''<ref>{{cite web|url=http://www.jernbanen.dk/damp_solo.php?s=1&lokid=319|archive-url=https://web.archive.org/web/20120516004836/http://jernbanen.dk/damp_solo.php?s=1&lokid=319|url-status=live|archive-date=2012-05-16|title=DSB&nbsp;E&nbsp;964 blev bygget af Nydqvist i 1914|work=jernbanen.dk|language=Danish}}</ref> DSB was so impressed with the performance of the E class that starting 1942, a further 25 locos were built by Frichs of Aarhus. The E class remained in service into the early 1970s. On the death of king Frederik IX the funeral train from Copenhagen to Roskilde on 14 January 1972 was double-headed by two class Es.

Both are owned by the Swedish Railway Museum. Several Frichs-built locomotives are preserved in Denmark, and E 996 at Railworld in Peterborough. F 1200 was involved in a serious accident outside Getå in October 1918.
